The KYB Gas-a-just quad-shock package is tailored for Ford Mustang applications with the 8.8-inch rear axle produced from 1979–2004, excluding 1999–2004 Cobra models. The monotube Gas-a-just shocks instantly adjust damping via an air-free hydraulic piston and a high-pressure nitrogen chamber with a floating piston, resisting aeration and restoring responsive control and comfort to maintain the vehicle's designed ride behavior.
